# Objective
Noticed a warning when running tests:
```
> cargo test --workspace
warning: output filename collision.
The example target `change_detection` in package `bevy_ecs v0.5.0 (/bevy/crates/bevy_ecs)` has the same output filename as the example target `change_detection` in package `bevy v0.5.0 (/bevy)`.
Colliding filename is: /bevy/target/debug/examples/change_detection
The targets should have unique names.
Consider changing their names to be unique or compiling them separately.
This may become a hard error in the future; see <https://github.com/rust-lang/cargo/issues/6313>.

## Solution
I renamed example `change_detection` to `component_change_detection`

Renamed from examples/ecs/change_detection.rs (Browse further)
